I have seen duplicate standby MACs cause 'address flapping' issues on a
cat4000 L2 switch. 2 3600 routers with multiple physical interfaces (no
trunks) were doing the HSRP. It was a year ago. I think the usebia option
may have fixed it, but I changed the standby and fixed it that way. It's
possible it was a code problem, but it was an all-Cisco environment, so PVST
was fully supported. So if you're having weird connectivity issues, check
your switch logs.

Exactly. For that matter, really the only time you need to use any
other number than, say, 1 is if you have multiple HSRP groups on the
same subnet (or VLAN). Other than that, you could use group number 1 on
all subnets (VLANs) because, in a sense, they are only "locally"
significant where "locally" means on a given subnet (or VLAN).

Actually, the 16 group limitation is the numbering limitation. It
simply means that you can only use 1-16 as group number but you have
have as many vlans running HSRP, all you have to dois recycle the group
number. It should not cause any issues.
